We're currently using Wicket 1.5.7, and have a need to display data in a treegrid structure. My question relates to validation of individual cell values. The Wicketstuff Treegrid works on a per column model, and ideally what I need is the ability to examine individual cells, and run defined validation rules against them. The values of the cells may possibly be validated against other cells, and any errors highlighted with appropriate styling e.g. red background. I'm not finding that the Treegrid is particularly easy to work with in this respect. Ideally it would be nice to attach a validator to an individual cell. Is this possible? I've not been able to find any examples which demonstrate how to do this.

Thanks
Andrew
